Where in the World Are Windows Phones Outselling iPhones? - NYTimes.com

tbd if Microsoft employee phones were included in the country-level counts...

"According to Kevin Restivo, an analyst at IDC, the countries where Windows Phone shipments exceeded those of iPhone during the fourth quarter were: Argentina, India, Poland, Russia, South Africa and Ukraine. A seventh “country” where Windows Phone shipments beat iPhone is actually a group of smaller countries, including Croatia, that IDC lumps together in a category called “rest of central and eastern Europe.”
Mr. Restivo provided some context, though, that slightly diminishes the scale of Microsoft’s success in those countries. Three of the markets — Ukraine, South Africa and “rest of central and eastern Europe” — are small enough that there were fewer than 100,000 Windows Phone unit shipments in the fourth quarter in each of them."
